If you have replaced the original tires that came with your SC please let me know what you went with and why?.

I am going to replace mine soon and wanted some real world experience from 430 owners.

Conventional vs Run Flat?
Different Speed Rating?
True All Season vs Summer?
Etc....

Thanks

 

After 21,000 miles on my Bridgestone RF (still another 5000 + of tread left), I decided to do a favor to my spine and get the Michelin Pilot Sport A/S. My Lexus dealer is picking them up for me at Discount Tires ($265 per) and is mounting them... reattaching sensors, and putting in truck kit..... as we speak!!!. As a loyal Lexus customer, and a friend of the Service Manager, they are giving me 50% discount on the 'spare' trunk assembly. Let me get a few miles under my belt, and I'll get back to you....All relevant threads on this forum give the Michelins A+

 

I second the Pilot Sport A/S: conventional, Z-rated, all-season ultra-performance. I now have about 500 miles on them in narrowly variable weather (from ~40F & pouring rain to ~60F sunny), and the ride quality and comfort, ride quietness, and handling are all vastly improved over the Potenza runflats.
